Mr. Gu's request was promptly accepted by Matins without hesitation.
It really was the kind of task they excelled in— at least one of them.
Interstellar warriors are formidable, sure, but a perpetual weakness is their lack of numbers.

No matter how tough a powered armor is, to be honest, it can't withstand a direct hit from a 155mm howitzer shell; no matter how powerful a bomb gun is, it may penetrate the locally-produced 'Challenger' tank with no big deal, but on top-tier battlefields, if it encounters the regular Lion Tanks of the Star Realm Army, much less the Lion King Tanks, it would be like scratching an itch.
They are a scalpel, not meant to be used as a hammer.
